The user can also directly check the operation of the target to be screened through the physical button or virtual button of the set top box or the television device. After receiving the instruction of the target to be screened by the user, the SI is parsed, the location information of the target to be screenshotd is obtained, and the target to be screenshotd is intercepted according to the location information.

As shown in FIG. 4, the method may further include: Step 3030: On the display screen, after the parsing of the SI, the location information of the to-be-screened target is obtained, and the target to be captured is intercepted, the method may further include: Step 3030: The user displays the range indicated by the location information. Specifically, the user may be prompted to display the wire frame at the boundary of the range on the display screen. The wire frame may be displayed at the boundary of the range; or the range may be displayed semi-transparently; or, within the range The hatching or the like is added, and the manner of the prompt is not specifically limited in the present invention.

In addition, the wireframe is displayed at the boundary of the range as an example: when the location information of the target to be screenshotd in step 301 includes only the relative abscissa and the relative ordinate of the target center point to be screenshotd, and the relative length and relative of the target to be screenshotd. In height, in general, the screenshot frame is square, and the side length of the square screenshot frame is equal to the relative length and relative height of the target to be screenshotd, respectively. The screenshot frame may also be a circle or an ellipse. When the position information of the target to be shot in step 301 further includes coordinates of several points on the outer edge of the target to be screenshotd, the screenshot frame is an irregular shape, and the irregular shape is approximately equal to the screenshot to be viewed. The display shape of the target, in which case the user can capture the picture he wants more accurately.

After the target image to be viewed by the user is displayed, the user issues a screenshot instruction at any time, and the set top box or the television device intercepts the image according to the screenshot instruction issued by the user. In general, the user issues a screenshot command via a remote control device that is associated with the set-top box or television device. The remote control device matched with the set top box or the television device may be a remote controller, or may be a mobile phone, a tablet and a computer keyboard light device that establish contact with the set top box or the television device through multi-screen interaction or other technologies and means. The user can also issue a screenshot command directly through the physical button or virtual button of the set top box or the television device. The way the user can issue the screenshot command can also be flexibly set. For example, press or click the screenshot button to take a direct screenshot, or press or click the screenshot button once to select the screenshot box, press again or click the screenshot button to take a screenshot, or Press the screenshot button for the first time to select the screenshot box. After selecting the screenshot box, the user can adjust the size of the screenshot frame. After the user has adjusted the size of the screenshot box, the user presses or clicks the screenshot button to capture the image.

After the image is captured, the captured image is typically stored in a predetermined folder or storage device. Optionally, after the intercepted picture is stored, the picture is extracted for sharing, transmitting, and the like.

304. Upload the intercepted picture to the headend server.

After the image is captured, the intercepted image is uploaded to the headend server, and after the intercepted image is uploaded to the headend server, the headend server counts the user's preference according to the object of interest of the user, so that the headend server can be based on the object of interest to the user. To count the user's preferences, and further expand and refine the objects that the user pays attention to according to the user's preferences, and vice versa, the objects that are not of interest to the user are summarized as targets to be screened or not to be targeted. For example, when the head end server counts that the user pays more attention to the face of the person, the element of the face of the person is further subdivided, and the subdivided element is used as the target to be shot, for example, the eyebrow, eyes, nose, mouth of the face of the person As the target to be screened, the cheeks and the like carry the position information of the objects to be shot in the extended SI, so that the user can capture the pictures of interest more accurately. On the other hand, when the head-end server counts that the user does not pay much attention to the landscape picture, the details of the landscape, such as mountains, rivers, trees, etc., are taken as the target of the scene, so that the user can pay more attention to the details of the picture that he is interested in.

As can be seen from the foregoing embodiment, the foregoing embodiment provides the method for the screenshot, by carrying the location information of the target to be shot in the display screen in the SI, and then parsing the SI to obtain the location information of the target to be shot in the display screen. And forming a dynamic tracking menu screenshot menu according to the location information of the target to be screened. After receiving the target instruction to be screened according to the screenshot menu, the user analyzes the si in real time, and displays the user in the form followed by the screenshot box. The selected target to be screened, so that the user can more intuitively view and select the image to be intercepted, and after receiving the user's screenshot instruction, intercept the image and upload the captured image to the head end, so that the head end can be based on the user's attention. The object counts the user's preferences, adjusts and refines the target of the screenshot, and makes the user's screenshot operation more precise, which improves the user experience.
